If I were to describe the 2 main focuses of Yume Nikki it's exploration and atmosphere, .flow takes the often weird and somewhat disturbing atmosphere of Yume Nikki, makes it more explicitly dark and horror focused to make a unique and intriguing game that easily stands on it's own. .flow makes me uncomfortable in ways that very few horror games have and for that it's quite great. If you liked Yume Nikki play this definitely.
